Abstract: Given a metric space $ \left( {X,d} \right)$ we study the existence of an ultrametric $ \delta $ which is dominated by $ d$. We give a number of examples and prove, among other results, that such an ultrametric exists if $ \left( {X,d} \right)$ is locally compact and totally disconnected.
